We review different exact approaches to string theory. In the context of the Green–Schwarz
superstring, we discuss the action in curved backgrounds and its supercoset formulation …

A bstract We study the integrable η and λ-deformations of supercoset string sigma models,
the basic example being the deformation of the AdS 5× S 5 superstring. We prove that the …

We use integrability techniques to compute structure constants in\(\mathcal {N}= 4\) SYM to
leading order at weak coupling and to leading order in the planar expansion. Three closed …

A bstract We study the deformed AdS 5× S 5 supercoset model of arxiv: 1309.5850 which
depends on one parameter κ and has classical quantum group symmetry. We confirm the …

We determine the off-shell symmetry algebra and representations of Type IIB superstring
theory on AdS 3× S 3× T 4 with mixed R–R and NS–NS three-form flux. We use these to …

A bstract We propose a procedure to derive quantum spectral curves of AdS/CFT type by
requiring that a specially designed analytic continuation around the branch point results in …

A bstract We examine a recently proposed class of integrable deformations to two-
dimensional conformal field theories. These λ-deformations interpolate between a WZW …

Abstract Building on arxiv: 0912.1723 [1], in this paper we investigate the AdS 3/CFT 2
correspondence using integrability techniques. We present an all-loop Bethe Ansatz (BA) for …

Conformal sigma models and Wess–Zumino–Witten (WZW) models on coset superspaces
provide important examples of logarithmic conformal field theories. They possess many …

Starting with the F ˆ/G supercoset model corresponding to the AdS n× S n superstring one
can define the λ-model of arxiv: 1409.1538 either as a deformation of the F ˆ/F ˆ gauged …
